Serial No. 147,003.

The invention relates to ice scoring ma chines of that type designed for the scoring of v large ice cakes so that they may be readily severed into smaller sections of predetermined size and weight.

In the present state of the art it is usual to score the large cakes both longitudinally and transversely and upon opposite sides of the cake. It is also usual to arrange the scoring saws on pairs of arbors which are upon opposite sides of the ice cake. This complicates the construction of the machine as it is necessary to drive all of the various arbors as well as to provide for relative movement between the arbors and the ice cake in trans verse directions.

It is the primary object of the present invention to simplify the construction by dispensing with one of the arbors holding the series of saws for transverse scoring. This is accomplished by a construction in which a single arbor provided with a series of saws is used for scoring the ice cake successively upon opposite sides thereof. A further object of the invention is to effect the relative movement between the ice cake and saws with a simple construction of mechanism thereby greatly reducing the cost of manufacture. lVith these and other minor objects in view the invention consists in the construction as hereinafter set forth.

Figure -9 is a diagrammatic sectional plan view.

As specifically shown my improved machine comprises a pair of A-shaped end frames A and A which are connected to each other by a series of longitudinally extending frame bars B. At the base and extending beneath this frame is a platform C 'on to which the ice cake may be fed longitudinally through the opening in oneof the A frames. D and D are the saws for longitudinally and centrally scoring the ice cake on opposite sides thereof which saws are mounted upon arbors E and E journaled in bearings on the frame A to be in advance of the point of entrance of the ice cake. Thus, the cake when fed on to the platform C within the frame will be longitudinally scored.

At a point above the path of the ice cake and near the apex of the frames A A, there is arranged to extend longitudinally and centrally an arbor F bearing a series of saws G, G etc. for effecting the transversescoring. The ice cake is brought into operative relation to these saws by first moving it laterallyfrom the centre of the frame to one "side thereof, then elevating it along guides parallel to this side of the frame so'as to pass the saws and to score one side of the cake, then moving the cake transversely to the opposite side of the frame and lowering it past the saws to score the opposite side thereof, such movement being accomplished as follows.-

H is a swinging frame comprising a pair of arms H, H arranged adjacent to the opposite end frames A, A and pivotally attached thereto at the points H The lower ends of these arms are connected by a shaft H on which is pivotally mounted apad or frame H for hearing against one side of the ice cake. As shown in Figure 2 theframe and pad are initially at the right and the pad is held in vertical position by hearing with its lower end against the stops H on frames A, A. In

this position the pad will becleared by the ice cake when fed longitudinally into the frame upon the platform 0.

At a certain point in the cycle of operation the frame H is swung to the left, Figure 3, this being accomplished by cams I upon a longitudinally extending shaft I journaled in hearings in the frame. This swinging movement will push the ice cake off from the platform C and up an inclined platform C substantially perpendicular with the side of the A-frame and into a position for being ele vated alongthis side of the frame. During this swinging movement the pad H being pivotally mounted on the shaft H, is free to framesand upon the right and left hand sides 7 at the base thereof. Thus, when motion is communicated to these chains the bar J will be moved up on the left hand side of the frame carrying the ice cake up with it and after passing around the sprockets K will descend on the. opposite side of the A frame lowering the ice cake therewith. t is however necessary to provide means for holding the ice cake while the bar J passes over the sprocket K and for transferring the cake from the left hand side to the right hand side of the frame. Sucha means is formed by the basket or receptacle L which is of a width corresponding to the ice cake and is open at its bottomto receive said cake. This receptacle is pivotally mounted on a shaft L journaled in bearings on upward extensions A of the frames A, A. There is also provided mechanism for swinging this basket from a position in align ment with the "left hand side of the frame to a position inalignment with the right hand side thereof This swinging movement is timed with the movement of the bar J so that when said bar has passed over the sprockets K the ice cake will be in a position to descend with said bar past the scoring saws G.

For accomplishing the various movements that have been described I have provided operating mechanism preferably of the following construction. M is a motor mounted on a bracket frame h attached to the frame A. M is a sprocket on the motor shaft which drives chain M passing about sprockets M M M arranged respectively ad]acent to the apex of the A frame and upon the left and right hand sides thereof. The sprockets M and M are connected by beveled gears M to the arbors E and E for the longitudinal scoring' saws D and D. The sprocket M is mounted upon the arbor F and forms the driving means therefor. Thus all of the scoring saws are simultaneously driven and at the same speed. I

At the opposite end of the arbor F adjacent to the frame A there is arranged a step down gearing N between said arbor and a shaft K on which the sprockets K are mounted. By means of this. gearing the chains 5 are simultaneously driven at a greatly reduced speed from that of the arbors. Upon the shaft K is a sprocket 0 connected by a chain 0 with a sprocket O which drives a step down gearing O for actuating the shaft I so that the said shaft is driven at a still further reduced speed. The timing of these parts is such that for one revolution of the shaft 1 the chains J and feed bar J also complete one full revolution. The swinging of the basket L from its position for receiving the ice cake to the position for discharging the sameis'preferably' effected by the following mechanism. P is a bell crank lever fulcrumed at P on the upward extension A of the frame A. One

arm P of this lever extends into the path of the feed bar J preferably engaging a roller P on said bar. The other arm P of the bell crank lever is connected by a link P to.

a pivot P on the basket L at one side of the shaft L. The parts are so proportioned that 7 after the roller P contacts with the arm. P the further movement of the rod J over the sprocket will swing the bell crank P and through the link P will rock or tilt the basket L. This will move said basket from a position for receiving the ice block to a position for discharging the same during (the time interval. in which the rod J is passing over the sprocket.

For intermittently feeding, the ice cakes lapse or fold downward during the rearward.

movement of said bar so as to slide under the ice cake in front of the machine. The mechanism foractuating the bar V includes a feed chain TV beneath the platform which in turn is driven through sprocket and chain con nection "W and through beveled gears N from a shaft V connected to the sprocket wheel K Further description of this mechanism will be unnecessary.

Cakes of artificial ice are usually oftapering form so as to be readily removable from the freezing cans but in longitudinally scoring the ice cakes it is desirable to form a kerf in the median plane or non parallel to the sides of the cake. To accomplish this ll preferably place upon the feed bar J a supporting member Q for the small end of the cake. See Figs. 1 and 6. This member, as showm is provided with an annular knife edge Q for biting into the ice and holding the cake from relative longitudinal movement. The member Q; is also preferably adjustable upon the shaft by means of set collars Q} secured on opposite sides thereof by set screws Q This permits of so adjusting the member Q, that it lever P to be rocked on its shaft L.

will support the small end of the ice cake at the proper height to score said cake along its median line.

Uomplete operation, of the machine In the complete operation of the machine the ice cakes are first placed on the platform in the path of the reciprocating feeder V which on its forward stroke advances the cake through the opening inYthe frame and in engagement with the longitudinal scoring saws D and D. The cake is guided during such advancement by guides V on the platform so that it will be directed into the machine adjacent to the pad H The amount of movement is slightly greater than required so that in the subsequent transverse movement, the cake must be drawn rearward to properly align it with the transverse scoring saws. This is efiected by an inclined spring bumper X at the forward end of the cake which presses it rearward against a guide X during the transverse movement under the ac tuation of the pad H When the cake is moved transversely to the left, Figure 2, its outer face will come into engagement with a spring guide Y which will press it toward the guide bars Y parallel with the A frames. This spring guide also holds the cake to the guides while it is being elevated and during the scoring operation. At the completion of the upward movement the cake is engaged with the basket L which is then actuated by the roller P bell cr%r11k 1e rocking-movement is sufficient to carry the cake into alignment with the guides on the opposite side of the frame and while this occurs the feed bar J, which has elevated the cake, moves over the sprocket K and begins its descent on the opposite side of the frame. The cake being supported solely by this bar J will be lowered with it passing the scoring saws G which score the opposite side of the cake in the planes of the scorings on the first side. Finally when the cake reaches the bot tom of the frame, it will rest upon the inclined platform Z upon which it slides to one side.

In order that the sections of the ice cake between the scores may be of approximately equal weight, the preferred machine has means to definitely locate the ice cake longitudinally with respect to the scoring saws. This is primarily accomplished by the mem' ber Q having a knife edge Q, which as previously described, bites into the bottom of the cake and holds the same from longitudinal displacement relative to the bar J. This bar J is also held from displacement preferably by providing at opposite ends thereof bearings J (Figs. 6 and 8) which slidably engage with guide surfaces on the frames A, A.

Obviously, the present invention is not re stricted to the particular embodiment thereof herein shown and described. Moreover, it
